Senior Software Engineer at YLD, based in the EU. I build AI/LLM integrations and Go microservices for clients in US banking and financial services. Eight years shipping production systems across GCP and AWS — from on-prem migrations to RAG platforms.
- AI & LLM integrations — RAG systems and agent orchestration with LangChain & LangGraph, Vertex AI, Gemini, and the Anthropic Claude API, backed by Neo4j and Qdrant.
- Software engineering — Go microservices on Kubernetes, Node.js and Python backends, React / Next.js / React Native on the frontend, TypeScript across the stack.
- Cloud & DevOps — multi-cloud on GCP and AWS, infrastructure as code with Terraform, CI/CD with Cloud Build, and a focus on reliability, cost, and observability.
